It would be difficult to exaggerate the benefit of this measure to the nation, through the service, despite the subsequent reactionary legislation. By a single act a large number of officers were advanced from the most subordinate and irresponsible positions to those which called all their faculties into play. "Responsibility," said one of the most experienced admirals the world has known, "is the test of a man's courage"; and where the native fitness exists nothing so educates for responsibility as the having it. The responsibility of the lieutenant of the watch differs little from that of the captain in degree, and less in kind. To early bearing of responsibility Farragut attributed in great part his fearlessness in it, which was well known to the service before his hour of strain. It was much that the government found ready for the extreme demands of the war a number of officers, who, instead of supervising the washing of lower decks and stowing of holds during their best years, had been put betimes in charge of the ship. From there to the captain's berth was but a small step. "Passed midshipman," says one of Cooper's characters, "is a good grade to reach, but a bad one to stop in." From a fate little better than this a large and promising number of young officers were thus rescued for the commands and responsibilities of the War of Secession. II NAVAL CONDITIONS BEFORE THE WAR OF SECESSION THE VESSELS Less far-reaching, because men are greater than ships, but still of immense timeliness as a preparative to the war, was the reconstitution of the material of the navy, practically coincident with the regeneration of the personnel. The causes which led to this are before my time, and beyond my contemporary knowledge. They therefore form no part of my theme; but the result, which is more important than the process, was strictly contemporary with me. It marked a definite parting with sails as the motive reliance of a ship-of-war, but at the same time was characterized by an extreme conservatism, which then was probably judicious, and certainly represented the naval opinion of the day. It must be remembered that the Atlantic was first crossed under steam in 1837, a feat shortly before thought impossible on account of coal consumption, and that the screw-propeller was not generally adopted till several years afterwards. In 1855 the transatlantic liners were still paddlers; but the paddle-wheel shaft was far above the water, and so, in necessary consequence, was much of the machinery which transmitted power from the boilers to the wheel. All battle experience avouched the probability of disabling injury under such exposure; not more certain, but probably more fatal, than that to spars and sails of sailing-ships. Despite this drawback, paddle wheel men-of-war were being built between 1840 and 1850. Our own navy had of these two large and powerful vessels, sisters, the _Missouri_ and the _Mississippi_.
